feat(turbo_json): add $TURBO_EXTENDS$ #10763

chris-olszewski · 2025-08-13T20:29:33Z

Description

This PR adds a new DSL keyword for array task definitions that alters the behavior when using extends in a package turbo.json. Usually a field from a package task definition will completely override the root field e.g.
Root: { "env": ["FOO"] }
Package: { "env": ["BAR"] }
Result: {"env": ["BAR"] }

If the package uses the new $TURBO_EXTENDS$ the root field value will be extended from instead of overridden. e.g.
Root: { "env": ["FOO"] }
Package: { "env": ["$TURBO_EXTENDS$", "BAR"] }
Result: {"env": ["FOO", "BAR"] }

This functionality allows for greater flexibility when specializing package task definitions without needing to copy/paste the shared values and remembering to update them if the root changed.

It is currently gated by turboExtends feature flag in the root turbo.json.

Reviewing this each commit individually in this PR is highly suggested. The actual feature add is all done in the final commit, the rest are prefactors.

The primary prefactors are:

Plumbing through future flags to be read at config time, but usable at task resolution time. This is necessary since this is set at root and needs to be known when reading task definitions from package turbo.jsons
Adding a new intermediate step for task definition creation named "processed". Removes a majority of the DSL concepts and validations that are exclusive to a single field. This paves the way for future extensions to the DSL.

Nerd note:
Technically, we could extend $TURBO_EXTENDS$ to additional fields that are monoids. Extension behavior is really:

let a = if extends {
  base
} else {
  mempty
}
a mappend b

The only interesting addition we could make would be around boolean fields which has 2 different monoids: any and all. Which one to choose would depend on the default value of the flag. e.g. cache defaults to false so we would want an any (or) behavior. I am not suggesting we do this, it is more confusing than it is worthwhile.

Testing Instructions

Added a fair amount of unit tests for the whole task definition resolution steps.

turborepo-tests/integration/fixtures/turbo-configs/interruptible-but-not-persistent.json

      "env": [
        "NODE_ENV",
-        "$FOOBAR"
+        "FOOBAR"


We changed validation order (both are still checked) and this turbo.json was invalid in 2 ways. Previously we were depending on the ordering of validations to see the expected error message around this task being interruptible, but not persistent.

Non-blocking: Let's be slightly more descriptive on this flag name since we're about to have $TURBO_EXTENDS$ and, separately, make the extends key more powerful. I could see a user being confused about which this refers to.

) ### Description TL;DR Allow for `"extends": ["//", "@acem/my-pkg"]` to allow for shared task configuration outside of the root. This PR adds non-root extensions of `turbo.json` files. We still require all `turbo.json` files to extend from root first, but now you can extend from an additional package `turbo.json` files. The task definitions are collapsed left to right with the right fields taking precedence. (This can be more powerful when using `$TURBO_EXTENDS$` added in #10763) We do have to check for cycles in `turbo.json` extends statements to ensure we can resolve the `extends` chain. Prefactor steps taken: - Splitting of the `RawTurboJson` schema into a root schema and a package schema. This removes the need for our ad-hoc checks of all fields in a package `turbo.json` that are invalid. (We were missing quite a few, for example you could put `globalEnv` in a package `turbo.json` and it would be silently ignored) - Changed ordering of task definition chain construction to first load all necessary `turbo.json` before fetching task definitions - Created a `Validator` struct which is used to share context which affect validation outcomes. This is necessary to feature flag this behavior I highly suggest reviewing each commit by itself as there is a lot of prefactor work that muddies the feature addition. ### Testing Instructions
